  • Blade tension on Hawks

    I have 2 Hawks, a G-426 and a 226VS Ultra. My problem seems to be getting the proper tension on spiral blades. First, I am currently using, at a blistering pace, FD spirals, #3 & #5's. I am breaking these very rapidly, but they do have very little flex before snapping. Secondly, I find that when I have the proper amount of tension, it is difficult to fasten the blade in the holder because there isn't enough blade left to feed into the bottom clamp; I am top feeder. To have enough blade material to clamp, I have to loosen the tension more than I'd like too. I clamp the top of the blade only enough into the top clamp to hold firmly, trying to provide as much blade material as possible to clamp into the bottom holder. I don't have a problem with straight blades, and can cut until the blades are dull. I only use the spirals on the 226VS Ultra as the G-4 has Ponzgai blade clamps which don't work for me with the spirals. I really love my Hawks, except for trying to use these FD spirals. Haven't tried Pegas spirals, but am sold on the Mod G blades. Been scrolling over 12 years, and always find something new to try and conquer.

    I have the pozgai clamps on the top only. I did not like them on the bottom. I like the FD straight end spirals if I have to use them.
    The fact that you don't have enough blade to work with tells me something is not adjusted correctly. I am assuming you compared the length of the spiral in question with the straight blades that are fine. When I set up a new blade type, I release the rear tension cam and the front tension.
    Put my blade in so that it bottoms out in the top and bottom clamp. Tension the front then go to the back and tension for the appropriate ping.
    From that point forward I only use the front release.

      WOW #3 and #5 spirals are big. Almost like a power rasp. I have a VS226 Ultra. What are you trying to cut? I want to see if I can duplicate.

        Talked to him yesterday after he was coherent. Very fortunately, it was dc current. He said ac current and would have ended differently. And it wasn’t a house. It was a converter box in a marina located on a deck cut into a 20’ high steep bank. They had to climb a ladder to get to it. And they were...

        Wow!!!! That is beautiful. Super job of sawing. If I worked it out correctly it took you less than a minute for each opening especially when I look at the amount of time it would take to saw the outline of the bear. Garry

        Thanks guys, I have a lot of HDU left over from my sign business in various thicknesses.
        HDU doesn't "fuse" or repair itself under heat or friction. Only acrylics and some PVC materials do that. Depending on what part of the world you are in, you would have to google HDU Distributors...
